Definitions

  • the invention relates to a tool adapter, in particular such, can be fixed with the hollow wall boxes.
  • Cavity wall boxes are tools to accommodate electrical installation parts, such as switches, sockets, distributors or the like in hollow walls under plaster.
  • the cavity wall boxes are made of plastic and are fixed by means of brackets or similar devices on the back of the cavity wall in the region of the opening.
  • brackets or similar devices To tighten the brackets or other fasteners are screws that can be tightened from the front.
  • brackets or other fasteners are screws that can be tightened from the front.
  • depending on the thickness of the cavity wall often requires a relatively long erweg, resulting in relatively long screwing times. Therefore, it is common for large quantities that the screwing done with the help of electric screwdrivers.
  • the hollow wall boxes usually have two diametrically opposed fixing devices and, accordingly, two accessible from the front of screws. Since the hollow wall boxes are intended only for housing and possibly laying down, they have no very high stability. The evasion of the hollow wall boxes to the outside is prevented by the shape of the opening into which they are inserted. Because the hollow wall box is located with its outer periphery at the edge of the opening. However, there is the possibility, especially in careless tightening the screw that the hollow wall box dodges inward.
  • the invention is based on the object to provide a way to simplify the setting of the cavity wall boxes.
  • the invention proposes a tool adapter with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the tool adapter can be used for fastening all elements that have a similar structure as a cavity wall box.
  • the tool adapter should be operated so that an electric screwdriver or a drill with a corresponding output element in Engagement is brought with the drive receiver. Since the adapter would rotate with the driven device of the screwdriver, it has a positioning device which can be brought into engagement with the hollow wall box and prevents the turning of the adapter. Then, the tightening of the screw of the fixing device can be done with the aid of a tool bit, which is inserted in the output receptacle of the tool adapter. It is possible to use different tool bits without changing the wrench.
  • the positioning not only serves to prevent the co-rotation of the tool adapter, but is also designed such that it prevents the escape of the wall of the cavity wall box inside.
  • the positioning of the tool adapter is designed such that it engages two diametrical locations of the cavity wall box, preferably on the inside of the wall of the cavity wall box.
  • the positioning device is designed such that it aligns the output receptacle with respect to the screw to be rotated by the tool bit. This is especially true when the tool adapter, which has a certain size, hinders the direct view of the tip of the tool bit.
  • the tool adapter can be designed according to a further feature of the invention such that the drive receiving and the at least an output receptacle are mounted in two parallel spaced plate elements. These plate elements can also serve to support the rotary connection between the drive receiver and the driven receiver.
  • a tool bit is already firmly inserted or arranged in the output receptacle.
  • the output receptacle is designed for replaceable attachment of a tool bit.
  • the invention proposes that the tool adapter has two drive shafts driven in the same direction, so that both screws can be tightened in one operation. It may be provided according to the invention that one of the two rotary joints, in particular also both rotary joints, have a type of slip clutch.
  • the rotary joint can be constructed in any way in which the rotary joint can be constructed.
  • a peripheral gear element for example a belt or the like.
  • a rubber band which is placed around the elements, can fulfill this task.
  • the tool adapter has a housing in which the transmission connection between the drive receiving and the at least one output receptacle is housed. For example, protruding out of this housing on the front of a hexagon, which is inserted into a drill chuck of a drill or in the corresponding hexagonal socket of a screwdriver instead of a bit. On the opposite side protrude only the two screwdriver bits with which the box is screwed.
  • the positioning device is formed on the housing, which can serve to position the tool adapter relative to the can.
  • the positioning device may have an at least partially formed skirt corresponding to the shape of the cavity wall box, which skirt is intended to rest against the inside of the wall of the can. This apron can already be effective when inserting the tool adapter before the screwdriver bits come into engagement with the screws of the can.
  • This housing can also serve to accommodate the aforementioned spirit level. This can be arranged in particular in a recess of the housing, on the one hand to arrange well visible and on the other hand to secure against damage.
  • FIG. 1 shows a side view of a tool adapter, with the aid of which two screws of fastening devices of a cavity wall box can be screwed simultaneously.
  • the tool adapter contains two mutually parallel plate elements 1, 2, in which a drive holder 3 and two output mounts 4 are rotatably mounted. Between the drive receptacle 3 and each of the two output receptacles 4 a rotary connection is present, which is formed in the embodiment of Figure 1 by a rubber ring 5.
  • This rubber ring which is placed around the two rotatably mounted parts with tension, has the advantage that it simultaneously forms a slip clutch.
  • FIG. 2 shows the plan view of the arrangement of FIG. 1, so that the plate to be seen is the upper plate 1.
  • the drive mount 3 has a hexagonal inner opening 6 into which a corresponding hexagonal projection of a drill can be inserted.
  • the output receptacles 4 also have hexagonal inner openings, which then serve for inserting tool bits in this case. These tool bits can be fixed axially, for example by snap rings or similar devices. They protrude at the bottom of the lower plate 2. This is not shown in detail. Instead of a hexagonal inner opening also round or square approaches may be present.
  • FIG. 3 shows part of an end view of a cavity wall box 8.
  • the hollow wall box 8 has a relatively thin outer wall. To guide the mounting screws but continuous channels are present, which are offset from the outer circumference of the cavity wall socket slightly inward. As a result, a pillar 10 is formed on the inside of the wall of the hollow wall box. At the diametrically opposite point the hollow wall box is a same pillar 10 available. On both sides of the pillar 10 therefore limiting edges 11 are formed.
  • the arranged on the underside of the lower plate 2 of the adapter pin 7, see also Figure 6, are dimensioned so that they come to these side edges 11 of the pillar 10 to the plant. Each pin 7 is thus at the transition zone between the inside of the wall and the side edge 11 of the pillar 10.
  • pins 7 form a positioning device, which serve for positioning of the tool adapter.
  • the pins 7, which are not shown to scale in the figures, are dimensioned so that they already cause a positioning of the tool adapter before the tool bits can engage in the two screws.
  • FIG. 7 now shows a side view of a tool adapter according to a further embodiment.
  • the tool adapter includes a housing 20 constructed and assembled from a front shell 20a and a rear shell 20b. At its right side in FIG. 7, the front side, a hexagonal projection 21 which is rotatably mounted in the housing protrudes out of the housing 20 and has the shank shape of a conventional screwdriver bit, ie a hexagonal cross section with a peripheral groove.
  • an apron 22 is formed, which is offset from the outer periphery of the housing 20 inwardly.
  • the axial extent of this skirt 22 is greater than the protruding from the back 23 length of the screwdriver bit 24.
  • the screwdriver bit 24 is housed in a recess 25 of the skirt.
  • a plurality of webs 26 are formed distributed over the circumference, which emanate from the back 23 of the housing 20.
  • FIG. 8 now shows an end view of the tool adapter of FIG. 7 from the left in FIG. 7.
  • the recesses 25 in which the screwdriver bits 24 are accommodated correspond to the shape of the usually used junction boxes, see also FIG. 3, from which it can be seen. that the openings for the screws of the junction boxes are housed in such columns. When inserting the tool adapter of Figure 7 to 9 in the flush box these columns are within the recesses 25th
  • the skirt 22 is, with the exception of the recess 25, a circular cylinder, but leaves at the top and bottom of the tool adapter a place free. On the inside of the skirt radially extending reinforcing webs 27 are formed. At the top of the tool adapter, which is also shown in the figures above, contains the Housing 20 has a recess 28 in the form of a notch. This notch is traversed by a dragonfly 29, which is thus visible from the front of the housing, but on the other hand is secured by the accommodation in this recess 28 against damage.
  • Figure 9 now shows a cross section along line IX-IX in Figure 7.
  • a first gear 30 is connected with this first gear 30 meshes with two other gears 31, which are also mounted in the housing. These mesh in turn with two outer gears 32, which are connected via a torque-limiting coupling with the output shots for the screwdriver bits 24.
  • the gears 32 are formed as sprockets and have two axial notches 33.
  • the shafts 34 on which they are mounted also have an axially extending notch into which pins 35 are inserted. These are pressed by a spring, which runs along a diameter, to the outside.
  • the tool adapter is used as follows.
  • the hexagonal projection 21 is inserted into a receptacle of an electric screwdriver.
  • the skirt 22 is inserted into a hollow wall box inserted into a hole in the wall.
  • the columns in which the screws of the hollow wall box are present come into the recess 25 of Apron 22 to lie. With the help of the dragonfly 29, the exact horizontal position is determined.
  • the skirt 22, the outer diameter of which corresponds to the inner diameter of the hollow wall box carries the tool adapter.
  • the screwdriver bits 24 come to lie in the drive recesses of the screws. Now the screwing process can begin. Once the screws are tightened, the torque limits between the sprockets 32 and the shafts 34 become effective. This allows the installer to recognize that the process has ended.
